Thermax steam-driven VAMs are available in single effect and double effect modes. In steam-driven chillers, the source of heat is saturated steam at pressures in the range of 0.5 Kg/cm2 to 10 Kg/cm2.
Single Effect Steam Driven Machine:
In the single effect machine, the gain in concentration of the absorbent is achieved in single step, i.e., it has only one generator.
In the double effect machines, the gain in concentration is achieved in two steps. The primary generator (referred as High Temperature Generator or HTG) produces vapour, whose latent heat is used to fire a secondary generator (referred as Low Temperature Generator or LTG).
Prochill hot water chillers are available in low temperature, medium temperature and high temperature driven modes. The compact Cogenie is also available, and is driven by low temperature water.
Hot water fired machines are used for process cooling, industrial and comfort air-conditioning. A popular application of hot water fired machines is Charge Air Cooling of DGs & Gas Turbines. These machines typically find application in cases where the hot water source is already present, as part of an industrial or commercial process. Hot water fired chillers are generally used in industries like: Chemicals, Pharmaceuticals, Paper, Textiles, Captive Power Plants, Steel, Hotels & Hospitals, Restaurants, Software Parks, Offices, Educational Institutions, Museums, etc.
Direct fuel fired double effect machines have a furnace as an integral part of the high temperature generator, where a variety of liquid or gaseous fuels can be fired to drive the absorption machine.
Direct fired vapour absorption machines find their application in hotels, restaurants, cineplexes, offices,
shopping malls, school buildings or industries where steam or hot water is not generated.
